Description :
ASHAION C 220 Na is a high-capacity, strongly acidic cation exchange resin in bead form, derived from crosslinked polystyrene with a gel structure. It contains sulfonic acid functional groups and is supplied in a moist condition in the sodium form. Designed for efficient hardness removal, it offers enhanced operating capacity and long service life, making it suitable for industrial and commercial water softening applications.
Application :
ASHAION C 220 Na is widely used in the sodium form for water softening applications. It can also be utilized in two-stage deionization systems as the cation exchanger in the hydrogen cycle after appropriate regeneration.

Storage :
Ion exchange resins require consistent care to maintain their effectiveness. It is essential to prevent the resin from drying out. During storage, regularly inspect the resin by opening the plastic bags and checking its condition. If the resin appears dry, add sufficient clean demineralized water to keep it fully moist at all times.
Safety :
Acid and alkali solutions used for regeneration are corrosive and must be handled carefully to prevent contact with the eyes and skin. When using any oxidizing agents, appropriate safety precautions should be taken to prevent accidents and protect the resin from potential damage.
